12500
20
40
6250
Answer is Right!
Answer is Wrong!
The correct answer is B. 20.
Current is the flow of charge per unit time. It is measured in amperes (A), where 1 ampere is equal to 1 coulomb per second.
In this question, we are given that a charge of 500 Coulomb flows in 25 seconds. Therefore, the current is 500 / 25 = 20 A.
Option A is incorrect because it is the total charge, not the current.
Option C is incorrect because it is the current if the charge flowed for 1 second, not 25 seconds.
Option D is incorrect because it is the current if the charge was 6250 Coulomb, not 500 Coulomb.
